[PATCH 1/2] PV hugepages - Xen patch
This patch enables support of hugepages in a pv Xen environment. It is against the latest xen unstable tree on http://xenbits.xensource.com. The patch assumes the guest is passing a physically aligned hugepage. It does reference counting on all the underlying pages.

[makedumpfile] extract vmcoreinfo from /proc/vmcore for Xen
Hi, --- background ---------------------------------------------------- * what the makedumpfile is: To shorten the size of the dumpfile and the time of creating the dumpfile, makedumpfile copies only the necessary pages for analysis to the dumpfile from /proc/vmcore. You can specify the kind of unnecessary pages with dump_level. If you want to shorten the size further, enable the

[PATCH 0/5] VT-d support for PV guests
...#39;iommu_pv'' boot parameter (disabled by default). I''ve added some python bindigs to allow xend to assign PCI devices to IOMMU for PV guests. For HVM guests this is handled in ioemu. Not sure if it makes sense to handle both cases in one place. The changes currently hook into get_page_type() in xen/arch/x86/mm.c to map/unmap IOMMU pages when the page types change. This might not be the apropriate place to hook these calls. The patches I''ve added are as follows: xen-vtd-unmap.patch --- Make the VT-d iommu_unmap_page() code actually do something close to useful....

page ref/type count overflows
With pretty trivial user mode programs being able to crash the kernel due to the ref counter widths in Xen being more narrow than in Linux, I started an attempt to put together a kernel side fix. While addressing the plain hypercalls is pretty strait forward, dealing with multicalls (both when using them for lazy mmu mode batching and when explicitly using them in e.g. netback - the backends are

[xen-unstable] Commit 2ca9fbd739b8a72b16dd790d0fff7b75f5488fb8 AMD IOMMU: allocate IRTE entries instead of using a static mapping, makes dom0 boot process stall several times.
Hi Jan, After commit 2ca9fbd739b8a72b16dd790d0fff7b75f5488fb8 AMD IOMMU: allocate IRTE entries instead of using a static mapping, booting dom0 stalls several times. Sometimes this results in RCU stall warnings from the dom0 kernel, hitting the "any" key, on normal or serial console, makes the boot continue for a while but it stalls several times. (It also stalls on shutdown BTW) I have
